Format: "Data Source=mydb.sqlite" .PARAMETER DatabaseFilePath The direct file system path to the SQLite database file. .PARAMETER Queries One or more SQL queries to execute. Can be provided via pipeline. Each query can be parameterized using @parameter notation. .PARAMETER SqlParameters Hashtable of parameters to use in queries. Format: @{"param" = "value"} Multiple parameter sets can be provided for multiple queries. .PARAMETER IsolationLevel Controls the transaction isolation. Default is ReadCommitted. Available levels: ReadUncommitted, ReadCommitted, RepeatableRead, Serializable .EXAMPLE Invoke-SQLiteStudio ` -DatabaseFilePath "C:\data\users.sqlite" ` -Queries "SELECT * FROM Users WHERE active = @status" ` -SqlParameters @{"status" = 1} .EXAMPLE "SELECT * FROM Users" | isql -DatabaseFilePath "C:\data\users.sqlite" #> function Invoke-SQLiteStudio { [CmdletBinding(DefaultParameterSetName = 'Default')] param ( ########################################################################### [Parameter( Position = 0, Mandatory = $true, ParameterSetName = 'ConnectionString', HelpMessage = 'The connection string to the SQLite database.' )] [string]$ConnectionString, ########################################################################### [Parameter( Position = 0, Mandatory = $true, ParameterSetName = 'DatabaseFilePath', HelpMessage = 'The path to the SQLite database file.' )] [ValidateNotNullOrEmpty()] [Alias('dbpath', 'indexpath')] [string]$DatabaseFilePath, ########################################################################### [Alias('q', 'Name', 'Text', 'Query')] [Parameter( Mandatory = $true, Position = 1, ValueFromRemainingArguments = $false, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, HelpMessage = 'The query to execute.' )] [string[]]$Queries, ########################################################################### [Alias('parameters')] [Parameter( Mandatory = $false, Position = 2, ValueFromRemainingArguments = $false, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, HelpMessage = 'Optional parameters for the query.' )] [System.Collections.Hashtable[]]$SqlParameters, ########################################################################### [Parameter( Mandatory = $false, HelpMessage = 'The isolation level to use.
